From: Short photoperiod modulates behavior, cognition and hippocampal neurogenesis in male Japanese quail

Effect of photoperiod in quail anatomical parameters. (A) Weight (in grams) of quail exposed to short (SP) and long (LP) photoperiod conditions. (B) Diameter of the cloacal cleft (in millimeters) for SP and LP birds. *p < 0.05, significant difference between short-photoperiod exposed birds and long-photoperiod exposed birds. Data are presented as mean ± S.D.
